The showrunner, celebrating his Emmy-nominated series at THR's nominees party, talks about the decision to extend the AMC drama and sounds off on the recent spate of companion series at his network: "This is it. ... When it's done, it's done."

Two days after AMC announced that it would split the final season of the hit show Mad Men into two seasons, creator Matthew Weiner attended The Hollywood Reporter's star-studded Emmy nominees party, where he spoke for the first time about the big change to his show's seventh season.

"It's a strategy from the network and I was told about it," he told THR at the West Hollywood event on Thursday night.

While the decision may not have been in his hands, Weiner told THR he's making the best of it.

"I found a way to work with it. That's all I can say. I think it's an opportunity," he added.

However, Weiner is very convinced that he won't be following in the footsteps of AMC's other shows The Walking Dead and Breaking Bad, which are both getting spinoffs on the cable network.

"There's no chance," he told THR with a smile. "No judgment against anybody else -- but this is it. This is the story. When it's done, it's done."

Weiner's show will air the first seven episodes, dubbed "The Beginning," in the spring of 2014 and the final seven, "The End of an Era," in spring 2015.

"Every season is a new story, and I don't want to get bored but I also don't want to let the audience down," said Weiner. "For me, I start over. And there's this kind of thing that happens with the audience every year where it's like they're very happy to see us back in the premiere, and when the new story starts around episode two they start getting antsy and then they get with it by episode three when they see it's a new story."
